Route 12

Route 12 is a desert-grassland crossover route that connects Aredia City and Route 13. Starting from the exit of Aredia City, there is a small portion of desert land. Afterwards, the rest of the route are covered by mild grass and high terrains. HM6 Rock Smash is required in order to continue progress on the route, while HM1 Cut is also necessary for reaching Nature's Den. The overall terrain of the route is slightly complicated, yet a wide range of Pokémon can be found.
